Merge tag 'rtc-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni: "This contains a few series that have been in preparation for a while and that will help systems with RTCs that will fail in 2038, 2069 or 2100. Subsystem: - Add tracepoints - Rework of the RTC/nvmem API to allow drivers to discard struct nvmem_config after registration - New range API, drivers can now expose the useful range of the RTC - New offset API the core is now able to add an offset to the RTC time, modifying the supported range. - Multiple rtc_time64_to_tm fixes - Handle time_t overflow on 32 bit platforms in the core instead of letting drivers do crazy things. - remove rtc_control API New driver: - Intersil ISL12026 Drivers: - Drivers exposing the RTC non volatile memory have been converted to use nvmem - Removed useless time and date validation - Removed an indirection pattern that was a cargo cult from ancient drivers - Removed VLA usage - Fixed a possible race condition in probe functions - AB8540 support is dropped from ab8500 - pcf85363 now has alarm support" * tag 'rtc-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (128 commits) rtc: snvs: Fix usage of snvs_rtc_enable rtc: mt7622: fix module autoloading for OF platform drivers rtc: isl12022: use true and false for boolean values rtc: ab8500: Drop AB8540 support rtc: remove a warning during scripts/kernel-doc step rtc: 88pm860x: remove artificial limitation rtc: 88pm80x: remove artificial limitation rtc: st-lpc: remove artificial limitation rtc: mrst: remove artificial limitation rtc: mv: remove artificial limitation rtc: hctosys: Ensure system time doesn't overflow time_t parisc: time: stop validating rtc_time in .read_time rtc: pcf85063: fix clearing bits in pcf85063_start_clock rtc: at91sam9: Set name of regmap_config rtc: s5m: Remove VLA usage rtc: s5m: Move enum from rtc.h to rtc-s5m.c rtc: remove VLA usage rtc: Add useful timestamp definitions rtc: Add one offset seconds to expand RTC range rtc: Factor out the RTC range validation into rtc_valid_range() ...
